Reece James William Topley (রিস টপলি) is an English international cricketer who plays for the England cricket team in white ball cricket as a left-arm fast medium bowler. He plays for Surrey in domestic cricket. Topley debuted for England in August 2015 against Australia, and represented the team at both the 2016 ICC World Twenty20 and 2023 Cricket World Cup. He plays for the Mumbai Indians in the Indian Premier League.

He was born on 21 February 1994 in Ipswich. He was educated at the Royal Hospital School. His father, Don Topley, was a first-class cricketer for Essex and Surrey. His father was also one of his teachers at Royal Hospital School, where he is a master of cricket. His uncle, Peter Topley, was also a first-class cricketer.

In June 2009, aged 15, Topley made the headlines when he was injured bowling in the nets at Loughborough University to England batsman Kevin Pietersen. Pietersen flat drove a delivery, which ended up striking Topley on the side of the head, knocking him to the ground. He was taken to Leicester Royal Infirmary where he required stitches to his ear and was kept in hospital overnight. Following the incident, Pietersen, whom Topley cited as his favourite player, gave the youngster his cricket bat with his signature on.

He made his Twenty20 International debut against Australia on 31 August 2015 and his One Day International debut, also against Australia, on 13 September 2015, taking figures of 0-33.

He kept his place in the ODI side for the series against Pakistan and played in all four matches. He picked up his first international wickets in the first match and finished with figures of 3-26, although it wasn't enough to prevent an England defeat. He had picked up one wicket in each of the next three matches, with England winning all three games. He played in the first T20 international between the two sides, and finished with figures of 3-24.
